* Menu of -D flags for enabling instrumentation, as a commented-out CFLAGS +=
setting for convenient testing.
* js_FindProperty and js_LookupPropertyWithFlags return indexes into the scope
and prototype chains, respectively, to support internal instrumentation, and
to pave the way for the return of the property cache (bug 365851)..
* jsutil.[ch] JSBasicStats struct and functions for computing mean/sigma/max
and auto-scaling histogram.
* JS_SCOPE_DEPTH_METER instrumentation for compile- and run-time scope chain
length instrumentation:
+ At compile time, rt->hostenvScopeDepthStats and rt->lexicalScopeDepthStats
meter scope chains passed into the compile and evaluate APIs.
+ At runtime, rt->protoLookupDepthStats and rt->scopeSearchDepthStats track
steps along the prototype and scope chains until the sought-after property
is found.
* JS_ARENAMETER uses JSBasicStats now.
* Added rt->liveScopePropsPreSweep to fix the property tree stats code that
rotted when property tree sweeping moved to after the finalization phase.
* Un-bitrotted some DEBUG_brendan code, turned some off for myself via XXX.
* Mac OS X toolchain requires initialized data shared across dynamic library
member files, outlaws common data, so initialize extern metering vars.
* Old HASHMETER code in jshash.[ch] is now JS_HASHMETER-controlled and based
on JSBasicStats.
* DEBUG_scopemeters macro renamed JS_DUMP_SCOPE_METERS; uses JSBasicStats now.
* Disentangle DEBUG and DUMP_SCOPE_STATS (now JS_DUMP_PROPTREE_STATS) and fix
inconsistent thread safety for liveScopeProps (sometimes atomic-incremented,
sometimes runtime-locked).
* Compiler-modeled maxScopeDepth will propagate via JSScript to runtime for
capability-based, interpreter-inlined cache hit qualifier bits, to bypass
scope and prototype chain lookup by optimizing for common monomorphic get,
set, and call site referencing a prototype property in a well-named object
(no shadowing or mutation in 99.9% of the cases).

His comments:
Here are the changes to JSRef to make it compile either as C or C++. Mostly the changes are to add missing casts (since C++ doesn't have implict conversion from void* to other pointer types nor implicit casts from ints to enumerations) plus a few random things like the use of "private" as a variable name.
There are a few other minor bug fixes; in particular:
* A long statement with and'ed conditions is reformatted to make it easier to remove other builtin objects (e.g. Date).
* A #if was added to jsscript.c for the JS_HAS_SCRIPT_OBJECT off case.
* In jsmath a #ifdef was changed to #if.
My notes also mention...
* jsobj.c should include jsopcode.h
* jsfun.c - doesn't link if JS_HAS_ARGS_OBJECT is off
* jsarray.c - a reference to js_ValueToSource should be conditional on JS_HAS_TOSOURCE
